Abstract
Description
Die Erfindung betrifft ein verspannbares Zahnrad mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a bracing gear with the features of the preamble of claim 1.
Aus Akustikgründen werden bei Verzahnungsstufen häufig verspannbare. Zahnräder eingesetzt. Verspannbare Zahnräder sind zweiteilige Zahnräder, bestehend aus einem Festrad und einem Verspannrad, die gegeneinander in Drehrichtung mit einer Federkomponente verspannbar sind. Das für das Verzahnungsrasseln verantwortliche Verdrehflankenspiel kann durch des Verdrehen des Verspannrades eliminiert werden, was zu einer deutlichen Verbesserung der Verzahnungsakustik führt. Verspannzahnräder werden beispielsweise beim Antrieb von Nockenwellen bzw. Ausgleichswellen in Brennkraftmaschinen eingesetzt.For reasons of acoustics, gear stages can often be braced. Gears used. Clampable gears are two-piece gears, consisting of a fixed gear and a Verspannrad, which are braced against each other in the direction of rotation with a spring component. The rotational backlash responsible for the gear rattle can be eliminated by twisting the Verspannrades, resulting in a significant improvement of the toothing acoustics. Verspannzahnräder be used for example in the drive of camshafts or balance shafts in internal combustion engines.
Normalerweise wird das Verspannrad außen, d. h. auf der von der Welle abgewandten Seite, auf einem Bund des Festrades radial gelagert und mit einem Sicherungsring bzw. einer Quick Lock Scheibe oder einem anderen Sicherungselement in axialer Richtung gesichert. Die Spannfeder wird typischerweise als Omega-Feder oder Torsionsfeder ausgeführt, das Festrad ist üblicherweise fest mit der Welle verbunden, das Verspannrad ist üblicherweise, wie oben dargestellt, am Festrad gelagert und axial gesichert.Normally, the Verspannrad outside, d. H. on the side facing away from the shaft, radially mounted on a collar of the fixed wheel and secured with a locking ring or a Quick Lock washer or other securing element in the axial direction. The tension spring is typically designed as an omega spring or torsion spring, the fixed gear is usually firmly connected to the shaft, the Verspannrad is usually, as shown above, mounted on the fixed gear and axially secured.
Ein gattungsgemäßes verspannbares Zahnrad ist beispielsweise aus der österreichischen Patentanmeldung
Aufgrund dieser gattungsgemäßen Anordnung von Festrad und Verspannrad ist die axiale Sicherung des Verspannrades zwingend erforderlich. Für die axiale Sicherung ist somit eine zusätzliche, kostenaufwändige Bearbeitung (Nut) am Festrad notwendig. Das zusätzliche Bauteil, das aus dem Stand der Technik bekannte weitere Federelement, beispielsweise ein Sicherungsring oder eine Quick Lock Scheibe, sorgt für einen erhöhten Handlingsaufwand in der Montage, was zu Mehrkosten führt. Darüber hinaus ist in vielen Fällen der Bauraum für diese axiale Sicherung nicht vorhanden oder kaum darstellbar.Due to this generic arrangement of fixed gear and Verspannrad the axial securing of the Verspannrades is absolutely necessary. For the axial securing thus an additional, costly machining (groove) on the fixed gear is necessary. The additional component, known from the prior art further spring element, such as a locking ring or a Quick Lock disc, provides for increased handling effort in the assembly, which leads to additional costs. In addition, in many cases, the space for this axial security is not available or hardly representable.
Aufgabe der vorliegenden Erfindung ist es, o. g. Nachteile zu vermeiden.The object of the present invention is o. G. To avoid disadvantages.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved by the feature in the characterizing part of patent claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen ausgeführt.Advantageous developments of the invention are set forth in the subclaims.
Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in einer einzigen Figur näher erläutert.In the following the invention with reference to a preferred embodiment in a single figure is explained in more detail.
Um Bauraum, sowie Herstellkosten zu sparen ist das Verspannrad
Weiter ist das Verspannrad
Durch die intelligente Anordnung des Verspannrades
Die Axiallagerung des Verspannrades
Aufgrund der erfindungsgemäßen Ausgestaltung kann das axiale Sicherungselement, ein Sicherungsring, eine Quick Lock Scheibe, oder ähnliches, entfallen. Zusätzliche Bearbeitungen, die für die Befestigung dieser Elemente erforderlich sind, können gänzlich entfallen. Die erfindungsgemäße Ausgestaltung führt somit zu einem reduzierten Handlingsaufwand aufgrund des Wegfalls eines Bauteils. Die Verwendung eines verspannbaren Zahnrades
